Yup. There are a couple other silly sentences in there that would only happen in a fantasy world. Some people like it since the strangeness of it helps them remember better, or they find it funny and a stress-reliever, and others think it's just nonsense. :P

I think the strangeness might help some remember better not only because it is silly, but because the words are used that aren't always used together, so then people can remember the words separately rather than them programming into their brains along with only certain phrases. That's my analysis, partly from my experience as well. Probably not needed really either, but I added it anyway.
Have a nice day/night :)

Odd sentences also test listening ability. We may not know the word, or we cannot make sense of the sentence. but we still write what we hear and learn a bunch from it because it takes us out of our other senses that we rely on like crutches.

Children learn in a similar way. There are plenty of childrens books that have animals that can talk, read, write, etc.
Take "Winnie the Pooh" for example.
Owl can read, Rabbit does gardening, Kanga can cook, etc.
It is just a fun and interesting way to learn words
